LT3015ET-5#PBF

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The LT3015ET-5#PBF is a negative linear regulator from Analog Devices, delivering up to 1.5A of output current with a typical dropout voltage of 310mV. It provides a fixed regulated output of -5V and operates within an input voltage range of -1.8V to -30V. The device features low quiescent current of 1.1mA, which drops below 1µA in shutdown mode. It incorporates precision current limit with foldback, thermal limit with hysteresis, and reverse output protection. The unit is housed in a 5-lead TO-220 package and supports operation across the -40°C to 125°C temperature range.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Procurement Notes

Verify the specific suffix ET-5 against official datasheets to confirm the fixed -5V output and TO-220 package configuration. Ensure compatibility with required thermal management solutions given the package type. Confirm lead-free finish status and RoHS compliance through manufacturer documentation before finalizing procurement specifications.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Selection Notes

Select this component when a stable negative voltage rail is required for analog circuits. The fixed -5V output eliminates external resistor networks needed for adjustable versions. Consider the TO-220 package for easier heat dissipation compared to smaller surface-mount options. Verify that the input voltage differential remains within limits to prevent excessive power dissipation at full load currents.
